Executing a file from the FreeCAD Python console
#Freecad examples code
Unfortunately, there are some subtle differences when executing a file in this manner, as opposed to the other methods, see my usage of the recompute() function in the later code examples. When complete, the file can be run by pressing ctrl-F6. You are then presented with a nice-looking editor window, into which you can paste one of the examples from this blog. You can load a Python script into FreeCAD using the normal GUI File Open. Hence, if you are experiencing problems with previously-good code that suddenly doesn’t work, it is worth restarting FreeCAD in case this fixes the problem. If FreeCAD encounters a problem with your script, it will generally give a sensible error message, however very occasionally a script can corrupt the internals of the program, so it fails to respond in the usual manner. If you make that change, it is necessary to exit & re-enter FreeCAD for the change to take effect. They are stored in the default location for scripts you can alter this to a directory of your choosing, by changing the ‘user macros location’ in the dialog box. Executing as a MacroĬlick on Macro then Macros… and you are given a list of Python macro files that can be executed.

If you want to see the box in its full 3-D glory, either use the GUI controls to change the viewpoint, or add the following 2 lines: FreeCADGui.activeDocument().activeView().viewAxonometric()įreeCADGui.SendMsgToActiveView("ViewFit") 2. The result is a bit underwhelming all you can see is the bottom left-hand corner of a square. In the FreeCAD Python console window, try entering: FreeCAD.newDocument("Unnamed") There are several ways of running a Python script in FreeCAD: 1. The examples here have been tested with FreeCAD v0.16, and the current version 0.18 Running Python code This is very much a work-in-progress, but hopefully will provide some useful pointers if you’re a Python programmer doing occasional 3D design. This is simple in theory, but a bit tricky in practice I’ll spare you the many frustrating false-starts I’ve made, and describe some simple ways of producing 3D objects from scratch in Python. Most packages support some form of scripting, so why not program my complete design from scratch, without touching the GUI? FreeCAD is a (free) 3D design package, with a comprehensive Python interface, so seems to be ideal… On a dialog, set 95 mm as extrusion length and click OK.3D CAD packages can be hard work there is a lot to learn, which can be a major problem for an infrequent user such as myself. Select the created sketch in model tree and execute pad. The viewpoint may change to 3D mode, so select zoom all to adjust the viewpoint. Then click Close on Task tab to finish sketch edit. The sketch will be fully contained and be displayed with green lines. And select coincident constraint to match the center of the circle with the sketch origin.
Select a center of the circle and a sketch origin. On displayed dialog, set 40 mm to constrain the radius. Drawing a circleĬlick the circle and select radius constraint.
Select circle and click 2 point on sketch plane to draw a circle. Ĭreate a new sketch plane and select XY-Plane in the dialog. Switch workbench to Part Design workbench. Please refer to " FreeCAD: Mouse operation setting". Note: FreeCAD has other modes like Inventor mode, Blender mode and touchpad mode.
